Issue with large archive HDD causes WinUAE to lock itself and Windows up
I have recently taken many single-file demos and zipped them up and used them as archived hard drives in WinUAE rather than ordinary folders with files, and I find that performance degrades fairly quickly. The largest such zip file is 349Mb of data compressed to something like 211Mb, with a few dozen demo files in it.
The problem is that when I run files from that zip file, or others like it with far smaller and fewer contents, when I reset the Amiga, the screen contents remain on screen for a moment after I've done so, and it then restarts normally after the dark grey blank screen. BUT, eventually, the dark grey screen stays and WinUAE locks up, and I can't even get the Windows Task Manager on the screen and my only option is to Ctrl-Alt-Del to restart Windows. It's hard to get logs for this as I don't know for sure when the freeze will happen, but it seems to have started since I decided to zip up folders into archive hard drives. I think my only option is to restore them to folders. |

Think about it Foebane. When you are adding in large archives WinUAE is having to mount them...
This takes time and will "freeze" WinUAE if you have many. ...and you went down this silly route just to save a few MBs I would definitely reverse your decision on this one. |

I had thought of taking the entire Foebane folder I use and archiving that to save space instead of zipping up smaller parts of that folder, but I am worried about losing the lot if the archive gets corrupted. What is my best option for archiving a huge amount of data (2.4Gb+) and being able to recover most of it if corruption occurs? RAR? 7Z? I know ZIP wasn't designed with data recovery in mind. |

I realise I'm going OT on this, but I really need advice on this matter, please.

2.4GB+ is huge?
I know I could go down the post office and buy a 16GiB USB stick for 5 quid. All this space saving you carry on about really makes me shake my head. |

If archive is mounted as a harddrive, whole archive needs to be unpacked and converted to internal directory tree. It can take long time and use lots of RAM and unless you use 64-bit WinUAE, there may be only few hundred megabytes of RAM left (32-bit processes usually have 1G to 3G of RAM free where everything must fit, including DLLs, winuae.exe etc.., depending on Windows version), especially if your config has lots of Z3 RAM.

Use an NTFS compressed folder? Transparent compression.
Compression rates not too bad. |

You can use hard disk file with NTFS compression. It would be faster access and you gain some space. Use zip for archiving only or small things like ADFs.

It's not just the archive/HDD aspect that I'm going back on, but the fact that I had other problems with the files once they were zipped. But since that's over with now, it is no longer a problem. The thing I find odd is only now I'm seeing the other half of the argument. Last week when I was zipping everything up, the people I was with were "go for it", but now the sane half have spoken, and I'm going back to uncompressed. It was only a measly six hundred or so Mb's saved anyway. |

Could the lock-up issue indicate a bug? If on resetting WinUAE unpacks the archive contents to memory again, without freeing the already-unpacked data, the amount of memory used will gradually increase each reset until you run out.

I've put the files back to their non-zipped state. It takes up more space, but it makes things easier generally.

I like the read-only aspect of optical media, although if I discover something that needs to be fixed, it irks me as I'll have to fix it and then burn the disc again. Patches don't really satisfy me. |

I'm sure that if you worked as a ditch digger Foebane you would insist on doing the job with a teaspoon.

I would avoid using compressors LHA, ZIP, RAR etc..
The best solution is to compress all demos individually with PowerPacker or CrunchMania. Once this is done you can copy all the file self-extracting to a HardFile from 2GB/4GB to keep the double or triple copies. Compressing these "full" HardFiles would be useless because the content is already compressed |

If you mean I would put in more effort than needed for a simple collection of files, then yes, I would. It's my only hobby, and once that's complete, I'll have nothing else to do in my free time.

But when you will reach the end Foebane ?
I strongly guess this hobby, luckily, will take to you much more time than you think I don't know what kind of demos are you considering, but if you consider them all You know, we have something in common I strongly guess i will reach "the end" at least between 10 years |

There will always be more demos I can add on top of my 640, but finding them will take time.
Also, I don't just collect any old demos, but ones I like personally. |
